COMBINED NUT-WRENCH AND TOOL.

SPECIFICATION forming part of Letters Patent N 0. 439,071, dated October21, 1890.

Application filed September 2, 1890. Serial No. 868,766. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM HENRY Hus- TON, a citizen of the UnitedStates, residing at Mexico, in the county of Audrain and State ofMissouri, have invented a new and useful Combinationrench, of which thefollowing is a specification.

This invention has relation to combinationtools, the objects in viewbeing to construct a tool upon the plan of a wrench, and to embody insuch construction not only an easilyoperated, durable, and efficientwrench, but also numerous other tools convenient to the mechanic.

\Vith the above and other objects in view the invention consists incertain features of construction hereinafter specified, and particularlypointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation of a wrenchconstructed in accordance with my invention. Fig. 2 is a lon git-udinalvertical section. Fig. 3 is a detail in perspective of the rod and pipeattachment. Fig.4 is a side elevation of the movable jaw-operatinglever. Fig. 5 is a side elevation taken reverse to that shown in Fig. 1.Fig. 6 is a view in perspective of a detached part of the wrench,showing the wire'cutter.

Like numerals of reference indicate like parts in all the figures of thedrawings.

in practicing my invention I employ a shank 1, which in cross-section isoblong or rectangular, and which has its inner end reduced and beveledto form a screw-driver 2. At its upper end the shank terminates in anordinary rigid wrench-head 3, which may be incased, when desired to'beemployed as a rod or type wrench, with a casing 4. (Shown in detail inFig. 3.) The casing 4 is U shape in cross-section, has its under surfaceserrated or toothed, as at 5, and the upper edges of its terminalsprovided with flanges 6 for embracing the upper side of the head. Aperforation 7 is formed in the sides of the casing and the head, and isdesigned to receive aremovable pin 8, whereby the casing is looked uponthe head. The rear end of the casing does not extend to the rear orhammer end or face 9 of the head, so that the device may 50 be used as ahammer regardless of the presence of the casing. Upon one side the shankis divided into a scale of inches 10, whereby the same is adapted toserve as a measure or rule.

11 designates the sliding jaw, which at its upper free end is providedwith a transverse groove or notch 12, whereby it is adapted to coactwith the teeth of the casing and serve as a nail-extractor. The movablehead 11 is provided with an opening which receives the shank loosely,and in front of the opening is provided with a depending orinwardly-disposed rack-bar 13, designed for contact with the edge of theshank.

At each side of the shank, near its center,

is secured a pair of ears 14, which embrace the rack-bar, and in frontof the same have pivoted thereinbetween a segmental shaped and toothedhead 15, the teeth of which engage the rack-bar, said head beingprovided in rear of the teeth with a plain untoothed surface 16, saidhead being formed upon the upper end of an inwardly-bent handle 17,which terminates at its lower end in a sharpened point 18, especiallyadapted for the blacksmith in preparing the hoofs of horses for shoes,or to be used as an ordinary punch. The head is provided belowits teethwith a recess 20. The latter is disposed and slightly inclined, and oneof the ears 14 is provided with a recess 21, also inclined and forming acutting-shoulder 22. The opposite ear has an opening 23. Wire may bepassed through the recesses of the lever and the ears, and maybeconveniently cut by a compression of the lever toward the shank. Byswinging the lever until the plain portion of the head is opposite therack-bar the removable jaw may be adjusted to adapt it to various sizedpipes and rods, and by returning the lever, 0 so that the teeth of thehead thereof engage with the rack-bar, said adjustable head or jaw maybe quickly raised or lowered to fit various sized rods, nuts, and pipes.It may also be used as a pair of pliers, performing 5 all the functionsof the same, for holding nails while being driven in convenient placesand as tongs to be used at the anvil.

A scale is formed upon one side of the face of the stock, as shown inFig. 1, which scale roo is standard, and by it the diameter of a pipe orrod inclosed by the jaws may be accurately ascertained.

The various useful tools embodied in this single device and usuallyemployed individually will be readily appreciated by all conversant withthe handling and use of handtools.

The lower edges of the ears 14 combine with the stock to form anefficient tri-square. A perforation is formed in one of the ears l4, andin the same is threaded a set-screw 25, the inner end of which hascontact with the head 15 of the lever 17. The two membersnamely, thestock and 1evermaybe adjusted apart by the screw and serve as a compass.

It will also be apparent that the wrench may be used for cracking nuts.

Having described my invention, what I claim is 1. In a wrench, thecombination, with the stock thereof terminating at its upper end in afixed head and a sliding jaw having means for operating the same, of aremovable U- shaped casing forinclosing the head and having its underside provided with teeth and its upper edges with flanges for embracingthe end of the head, said casing and head being perforated and aremovable pin passed through the same, substantially as specified.

2. In a wrench, the combination, with the stock terminating at its upperend in a head, a pair of bearing-ears projecting from the stock,

and a hand-lever terminating in a partiallytoothed and partially-plainhead pivoted between the ears, of a jaw mounted for sliding upon thestock above the ears and provided with a rack-bar passing between thestock and head of the lever and having its teeth engaged by those of thehead, substantially as specified.

3. In awrench, a stock having a standard gage of rods and pipes stampedupon one side thereof and terminating at its upper end in a thick head,a sliding jaw mounted for movement upon the slot over the scale, andmeans for operating said jaw, substantially as specified.

4. In a wrench,the combination,with a stock, a sliding jaw having arack-bar, and a pair of ears projecting from the stock embracing therack-bar, one of said ears having an opening and the other an inclinedslot terminating in an inner cutting-shoulder, of a lever pivotedbetween the ears and having teeth for operating in the rack-bar, and aslothaving a cutting-shoulder adapted to coact with the shoulder in theslot of the ear, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in presence of two witnesses.

IVILLIAM HENRY HUSTON.
